Boot camp assistant doesn't recognize the Windows 10 iso file.

Can you post the MD5sum? Here is an example (using a different ISO file).

You can do this in Terminal.

• Start Applications -> Utilities -> macOS Terminal
• Enter 'openssl md5'
• Use macOS Finder to find the ISO
• Drag the file to the Terminal window, and press enter.

openssl md5 Win10_1909_EnglishInternational_x64.iso 

MD5(Win10_1909_EnglishInternational_x64.iso)= d1f08aea37586702f6fbe2fe3ea8c3fd

Obtain official Microsoft images, untouched.

You could use the Microsoft tool for this, or a website like this: https://tb.rg-adguard.net/public.php

You can verify yourself that all images are downloaded straight from Microsoft.

Did you check if your file is at least exactly 6221846528 bytes?

I have worked with the same on Big Sure 11.1 and it is recognised.

Where did you obtain the W10 ISO from? What is the name and MD5sum of the ISO?

I found the MD5sum, but I don't have a chance to get to the second line. After I put in the first line with the correct file name and return it, I get the response, "No such file or directory."

Did you drag & drop the Windows .iso file onto the Terminal window so it auto-fills the correct path to the .iso file?

You are not in the correct folder containing the ISO. This is what you should get.

openssl md5 Win10_20H2_v2_English_x64.iso
MD5(Win10_20H2_v2_English_x64.iso)= 10d50d88fac6306a00ddb41e983a046b

You should not need another license of Windows 10. The Audio issue is unrelated to your Office 365 issues.

Can you post a screen shot the of file in Downloads? If the file has a .downloads extension, then the download failed or is partially complete.
